Answer: -192.
Explanation:
3 + 56 - 323 -- 43 -- 43 - 54 - 3
First, let's deal with the double negative signs:
3 + 56 - 323 + 43 + 43 - 54 - 3
Now, perform the addition and subtraction from left to right:
(3 + 56) - 323 + 43 + 43 - 54 - 3
59 - 323 + 43 + 43 - 54 - 3
Now, continue to simplify:
(59 - 323) + 43 + 43 - 54 - 3
(-264) + 43 + 43 - 54 - 3
Finally, perform the remaining additions and subtractions:
-264 + 43 + 43 - 54 - 3
-264 + 129 - 54 - 3
-135 - 54 - 3
-189 - 3
-192
So, the final result is -192.
Hope it helps
